Mozilla has a service that promises a layer of anonymity from marketing firms that may sell your email. Well, I've tried it numerous times and it is a rejected domain. So, don't waste your time. I don't think this will improve because Mozilla doesn't engage feedback from users, has obtuse and stale "support" options. Apparently they rely on guidance from a insular club of selected "experts". This is typical for software companies, the neophyte public is incidental to their operation and really prefer to service their rewarded cheering section.
Tip for consumers:
Lack of efficacious help for the neophyte permeates the Mozilla culture.
